Direct growth of vertically aligned carbon nanotubes on a planar carbon subst…

Abstract. Uniform, vertically aligned multiwalled carbon nanotube arrays (VACNTs) were grown on glassy carbon-like thin films by thermal chemical vapour deposition (CVD). Thin (5 nm) aluminum and iron catalyst layers were pre-deposited by evaporation on the carbon substrates and VACNTs were grown at 750 oC by water-assisted CVD using ethylene as the carbon source. The aluminum layer was s…
